THREE:"I hope there is nothing wrong, sir," asked Prout.According to Sir A. Grant, it is by the mystical and poetical side of his nature that Plato differs from Aristotle. The one aspired to a truth above the truth of scientific knowledge; the other to methodised experience and the definite.182 Now, setting aside the question whether there is any truth above the truth of scientific knowledge, we doubt very much whether Plato believed in its existence. He held that the most valuable truth was that which could be imparted to others by a process even more rigorous than mathematical reasoning; and there was no reality, however transcendent, that he did not hope to bring within the grasp of a dialectic without which even the meanest could not be understood. He did, indeed, believe that, so far, the best and wisest of mankind had owed much more to a divinely implanted instinct than to any conscious chain of reflection; but he distinctly293 asserted the inferiority of such guidance to the light of scientific knowledge, if this could be obtained, as he hoped that it could. On the other hand, Aristotle was probably superior to Plato as a poet; and in speaking about the highest realities he uses language which, though less rich and ornate than his masters, is not inferior to it in force and fervour; while his metaphysical theories contain a large element of what would now be considered mysticism, that is, he often sees evidence of purpose and animation where they do not really exist. His advantage in definiteness is, of course, indisputable, but this was, perhaps, because he came after Plato and profited by his lessons.
